The language settings are stored in /User/Library/Preferences/com.apple.Preferences.plist which is on the user partition and isn't sandboxed off from third-party applications. Enabling Emoji everywhere is a simple matter of adding the KeyboardEmojiEverywhere key to this file and giving it a value of true.
